The changes in power production and power consumption are driving the intelligent upgrade of the grid, and the latest 4.5G wireless technology is becoming an important support for the transformation of the power grid by virtue of its access, economic convenience, safety and reliability. Recently, analyst firm Frost & Sullivan and Huawei released a white paper on "Wireless LTE Private Network to Build Smart Grid", analyzed how the basic communication network and the power grid evolve together, and explained how the smart grid can use the LTE wireless private network to accelerate the change. The emergence of new generations of renewable energy, such as the increase in renewable energy and charging piles and user microgrids, is presenting an unprecedented challenge to the development of the power grid. The global smart grid development is at a different stage. In developed countries and fast-growing economies, distribution automation is the focus of investment. By creating an intelligent, interconnected basic communication network, distribution automation will provide the grid with a real-time visible and always-controlled intelligent digital communication network. Flexible power (AMI) extends the consumption measurement and control of the network to the end customer and provides two-way metering through the deployment of the communication network. AMI is now mature in Europe and North America, while demand in emerging markets such as South America and Asia has soared. Therefore, in order to better promote the construction of a fully automatic and efficient smart grid, a high-performance, highly reliable and flexible communication network is the key. Frost & Sullivan recently released a white paper on "Wireless LTE Private Network to Build Smart Grid", analyzing the synergistic development trend of wireless communication networks and power grids, and expounding how power applications including distribution automation and smart meter reading AMI can accelerate intelligence by using LTE wireless private networks. Change. "4.5G wireless technology is the world's leading wireless communication technology, with the most mature industrial ecology and supports the evolution towards 5G. 4.5G technology has been widely used in the global carrier market and some vertical industry markets, including power companies. Building a secure, cost-effective, basic communications network," said Sheridan Nye, principal analyst for digital transformation at Frost & Sullivan. "As a result, 4.5G wireless networks are becoming a cost-effective alternative to fiber optics, and wireless networks avoid the cost of laying cables. It provides a more flexible networking and better performance than other wired and private wireless technologies." The basic communication network of the smart grid must be safe and reliable, and the 4.5G-based wireless private network will provide a better choice for the power industry. It not only has the characteristics of high security, low delay and wide coverage, but also supports continuous 5G. Evolution. Peng Jianhua, president of Huawei's enterprise wireless business, said: "Integrated utilization of licensed and unlicensed spectrum to achieve integrated bearer for broadband access and narrowband IOT services, 4.5G technology will provide a better choice for the grid. Huawei's eLTE based on 4.5G The SmartGrid solution has been applied in leading power business markets such as China, Latin America and Europe." The LTE wireless private network can be self-built and used by the power companies, which can better control and rationally develop the business. Ms. Nye added: “The power industry has realized the advantages of LTE. I believe that over time, 4.5G wireless networks will become the core service bearer network for many vertical industries including smart grids.â€

As a TWS earbuds, the sound quality is naturally one of the important criteria for judging its excellence. However, different people like different kinds of music, so they have different preferences for sound quality. For example, some people like the deep bass, some people prefer the shock of the high pitch, etc., so this piece is more subjective.
